Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A system for yielding control of a network to a device configured to operate on a PSTN, the system comprising: a network configured to couple one or more devices to the PSTN; a first device coupled to the network and configured to operate on the PSTN; a second device coupled to the network and configured to operate on the PSTN; a third device coupled to the network, configured to provide a VoIP interface between the network and the Internet and to provide a dial tone to the network; and a fourth device coupled between the network and the third device, and configured to detect when the second device attempts to use the network during a time when the first device is using the network.
A system allows a device (like a security system) that normally uses a traditional phone line (PSTN) to take control of a network. The system includes: a network connecting devices to the PSTN; a first PSTN device (e.g., a phone) on the network; a second PSTN device (e.g., a security system) on the network; a VoIP gateway providing a dial tone and a connection to the Internet; and a detector between the network and VoIP gateway that identifies when the security system tries to use the network while the phone is already in use.
2. The system of claim 1 , wherein the third device and the fourth device are incorporated into a single device.
The system described previously where a device seizes control of a network includes a VoIP gateway and a detector combined into a single device. This combined device provides a dial tone, an Internet connection via VoIP, and detects when a second PSTN device attempts to access the network while another device is already using it.
3. The system of claim 1 , wherein the fourth device detects that the second device is attempting to access the network based on detecting a sequence of DTMF signals on the network.
In the system that allows a PSTN device to seize network control, the detector identifies the second PSTN device's attempt to access the network by recognizing a specific sequence of DTMF signals (touch tones) sent over the network. This sequence acts as a signal that the security system is trying to initiate a connection.
4. The system of claim 1 , wherein the second device generates a predetermined sequence of DTMF signals when attempting to access the network.
In the network control system, the second device (e.g., the security system) generates a specific, pre-defined sequence of DTMF signals (touch tones) when it attempts to access the network. This predetermined sequence acts as a request to take control of the line.
5. The system of claim 4 , wherein the sequence of DTMF signals corresponds to a telephone number of a remote location.
In the network control system, the DTMF signal sequence generated by the second PSTN device when attempting to access the network represents the phone number of a remote location. This allows the system to identify the intended recipient of the security system's call.
6. The system of claim 1 , wherein the fourth device determines that the second device is attempting to access the network when the fourth device detects the predetermined sequence of DTMF signals.
In the network control system, the detector determines that the second PSTN device is trying to access the network specifically when it detects the pre-defined sequence of DTMF signals. Detection of this specific sequence triggers the line seizure process.
7. The system of claim 1 , wherein the fourth device transmits a signal when the fourth device detects the second device attempting to access the network.
In the network control system, the detector transmits a signal when it detects the second PSTN device attempting to access the network. This signal indicates that the second device is requesting control of the network.
8. The system of claim 7 , wherein the signal is a wireless signal.
In the system that allows a PSTN device to seize network control, the signal transmitted by the detector is a wireless signal. The wireless signal informs the system that the second PSTN device is attempting to access the network.
9. The system of claim 7 , wherein the first device is disconnected from the network when the fourth device transmits the signal.
In the network control system, the first PSTN device (e.g., the telephone) is disconnected from the network when the detector transmits the signal. This disconnect allows the second PSTN device (e.g., the security system) to use the network.
10. The system of claim 9 , wherein the fourth device sends a second signal when the second device is no longer using the network and the first device is reconnected to the network when the fourth device transmits the second signal.
In the network control system, the detector sends a second signal when the second PSTN device (e.g., the security system) is finished using the network. The first PSTN device (e.g., the telephone) is then automatically reconnected to the network when this second signal is transmitted.
11. The system of claim 7 , further comprising a fifth device connected between the first device and the network, the fifth device disconnecting the first device when the fifth device receives the signal.
In the network control system, a fifth device is located between the first PSTN device (e.g., the telephone) and the network. This fifth device disconnects the first device from the network upon receiving the signal from the detector, which indicates that the second PSTN device is attempting to seize control.
12. The system of claim 1 , wherein the fourth device is incorporated in the first device.
A system for managing data processing operations includes a first device configured to receive data from a second device and transmit the data to a third device. The system also includes a fourth device that processes the data before transmission to the third device. The fourth device is integrated into the first device, forming a unified structure. The first device may include a communication interface to facilitate data exchange with the second and third devices. The fourth device performs operations such as filtering, encryption, or compression on the data before it is sent to the third device. This integration reduces latency and improves efficiency by eliminating the need for separate data transfer steps between the first and fourth devices. The system ensures secure and optimized data handling, particularly in environments where real-time processing is critical, such as industrial automation, telecommunications, or cloud computing. The unified design simplifies deployment and maintenance while enhancing performance.
13. The system of claim 1 , wherein the fourth device sends the signal as long as the second device is using the network.
In the network control system, the detector continues to send the signal as long as the second PSTN device (e.g., the security system) is actively using the network. This continuous signal ensures the first device remains disconnected.
14. The system of claim 1 , wherein the second device generates the predetermined sequence of DTMF signals when the second device detects that the first device is using the network.
In the network control system, the second PSTN device (e.g., the security system) generates the pre-defined sequence of DTMF signals (touch tones) specifically when it detects that the first PSTN device (e.g., the telephone) is already using the network. This ensures line seizure only occurs when necessary.
15. A method of seizing control of a network configured to interface with a PSTN, the method comprising: transmitting, by a first device, a sequence of DTMF signals over the network; detecting the sequence of DTMF signals; disconnecting a second device from the network when the detected sequence of DTMF signals matches a predetermined sequence of DTMF signals; and communicating, by the first device, over the network following the disconnecting of the second device from the network.
A method for taking control of a phone network connected to a traditional phone system (PSTN) involves: sending a sequence of DTMF signals over the network from a first device; detecting that DTMF sequence; disconnecting a second device from the network if the detected sequence matches a pre-defined sequence; and then, the first device communicating over the network after the second device is disconnected.
16. The method of claim 15 , further comprising, transmitting a disconnect signal when the sequence of numbers matches the predetermined sequence of DTMF signals.
The method for seizing network control described above, where a first device transmits DTMF tones, includes transmitting a disconnect signal when the received DTMF tone sequence matches the predefined sequence. This disconnect signal triggers the disconnection of the second device.
17. The method of claim 15 , further comprising, transmitting a reconnect signal when the first device finishes communicating over the network.
The method for seizing network control, where a first device transmits DTMF tones and disconnects a second device, further includes transmitting a reconnect signal when the first device is finished communicating over the network.
18. The method of claim 17 , further comprising receiving the reconnect signal and reconnecting the second device to the network following receiving the reconnect signal.
The method for seizing network control, where a first device transmits DTMF tones, disconnects a second device, and sends a reconnect signal, further includes receiving the reconnect signal and automatically reconnecting the second device to the network upon receiving that reconnect signal.
19. A VoIP security system, comprising: a network comprising a first wire and a second wire; a security system configured to operate on a PSTN, the security system coupled to the first wire and the second wire; a PSTN telephone coupled to the first wire and the second wire and configured to operate on the PSTN; a VoIP interface device coupled to the first wire and the second wire, configured to provide a VoIP interface between the network and the Internet and to provide a dial tone to the network; a detector coupled to the first and the second wire, configured to detect when the security system attempts to access the network and send a signal indicating that the security system is attempting to access the network during a time when the PSTN telephone is using the network; and a device coupled to the first and the second wire, configured to disconnect the PSTN telephone from at least one of the first wire and the second wire based on the signal.
A VoIP-based security system includes: a network with two wires; a security system connected to the wires; a telephone connected to the wires; a VoIP device providing a VoIP connection and dial tone; a detector connected to the wires to detect when the security system tries to access the network while the telephone is in use, and to send a signal; and a device to disconnect the telephone based on that signal.
20. The VoIP security system of claim 19 , further comprising an access detector configured to detect the security system attempting to access the network and to generate the signal when the security system is attempting to access the network.
The VoIP security system described above, comprising a network, security system, telephone, and VoIP interface, uses an access detector specifically designed to detect when the security system tries to access the network. This access detector generates the signal that triggers the disconnection of the telephone.
21. The VoIP security system of claim 20 , wherein the access detector generates a second signal when the security system finishes accessing the network, the device reconnecting the telephone to the network upon receiving the second signal.
The VoIP security system with network, security system, telephone, and VoIP interface has an access detector which also generates a second signal when the security system finishes accessing the network. Upon receiving this second signal, the device automatically reconnects the telephone to the network.
